What about pressure treated 2x4 or 2x6? Those are still considered
soft wood right?

Wrong. Where you are, PT is Southern yellow pine. Depending on
species - there are several lumped into "Southern yellow pine" - it
can vary from hard to hard as a rock.

Unless it's extremely old, any new PT will still be quite soft
compared to, say, oak. Even dried PT SYP isn't the density of old,
virgin-growth SYP that is legendary as it is harvested from very fast-
growing young trees and simply doesn't have the narrow growth rings of
old-forest timber. It's harder than spruce and the other common
"whitewoods", granted, but it ("it" being PT) won't be a challenge for
a pneumatic gun--it's simply too new if it's PT and since OP is doing
major renovation/construction, he's looking more at brand-new than
really old, anyway.

Given an older (60+, say) structure, I'd agree it could be an issue...

Just yesterday I was cobbling together a PT plinth for a cabinet in my shop.
There were two pieces I could *NOT* get a nail through with a 26 oz. hammer.
Had to drill holes. Hard as a rock SYP still exists.
